Coulometric Titration of Urea with Electrogenerated Hypobromite

Urea impedimetric biosensor based on reactive RF magnetron sputtered zinc oxide nanoporous transducer

“…Increasing in urea level in blood and urine can cause urinary tract obstruction, dehydration, shock, burns, and gastrointestinal bleeding, whereas reducing in urea level may be seen in nephritic syndrome, cachexia and hepatic failure [2]. The assay of urea can be followed by many different techniques as spectrometry [3][4][5], potentiometry [6][7][8][9], conductometry [10][11][12], coulometry [13] and amperometry [14]. Nowadays several attempts have been widely done to develop urea electrochemical biosensor, due to their inherent advantages such as robustness, easy miniaturization, excellent detection limits, and requirement for very small amounts of analyte [15][16][17][18][19][20].…”

Novel I–V Disposable Urea Biosensor Based on a Dip‐coated Hierarchical Magnetic Nanocomposite (Fe3O4@SiO2@NH2) on SnO2:F Layer

“…Diagnosis of some diseases such as kidney and liver malfunction, as well as the prediction of the nature and causes of diabetes, needs regular monitoring of urea . Many different techniques such as spectrometry, potentiometry, conductometry, coulometry, impedimetry, and amperometry are being widely applied for urea monitoring. Currently, numerous methods are being extensively exploited to develop electrochemical biosensors for urea based on immobilized urease (Urs) enzyme, because of their inherent advantages such as robustness, simple miniaturization, exceptional detection limits, and the requirement for very small amounts of the analyte.…”

Rapid detection of total nitrogen content in soy sauce using NIR spectroscopy

“…Traditional analytical methods for the determination of total nitrogen content in soy sauce are Kjeldahl nitrogen determination (Hiller et al 1948) and sodium hypobromite (Kato et al 2013) methods. However, these methods are time consuming and tedious.…”
